Coronary Restenosis Clinical Trial
Official title:
A Prospective, Randomized Trial Evaluating Slow-Release Formulation TAXUS Paclitaxel-Eluting Coronary Stent in the Treatment of In-Stent Restenosis
The objective of this study is to evaluate the safety and effectiveness of the TAXUS Express2 Paclitaxel-Eluting Coronary Stent System as compared to brachytherapy in patients experiencing in-stent restenosis.
Percutaneous approaches to in-stent restenosis (ISR) have included balloon angioplasty
alone, rotational atherectomy, cutting balloon angioplasty, directional coronary
atherectomy, excimer laser angioplasty, placement of a second stent or any combination
thereof, and intra-coronary brachytherapy. Of these, only brachytherapy has been shown to
reduce recurrent restenosis after PCI for ISR, - and is now considered the standard of care.
Logistical considerations in establishing and maintaining a radiation program have limited
the widespread availability of this modality. These considerations include the need for
involvement of radiation oncologists, physicists, and safety officers; nuclear licensing
requirements; need for increased shielding and safety training; equipment and procedural
complexities; as well as increased procedural time and costs. Furthermore, recurrent ISR
after brachytherapy may still occur. Stent based drug delivery for the treatment of ISR
holds promise as a much simpler, safer and potentially more effective alternative to
brachytherapy.
This is a prospective, randomized (1:1), open-label, multicenter, safety and efficacy trial
for the treatment of in-stent restenosis. The primary objective is to demonstrate a superior
or non-inferior 9-month target vessel revascularization (TVR) rate for TAXUS-SR stent
compared to intra-coronary brachytherapy (beta source).
